Application filed June 19,

To all whom it may concern: Be'it' known that ,I, ARTHUR SMITH,

Icitizen'of the United States, and resident of chines, of which the following is a. 'specification.

" My invent-ionrelates more particularly to tabulating devices for t newriting machines.

One object of the invention is. to provide improved column selecting mechanism which may be set so that when the traveling element or carriage is released from its feed devices said element will be arrested by the engagement of the selected'column stop with the Cooperating stop member, all the column stops which maybe intermediate the selected column stop and the cooperating stop memher being skipped or passed.

Another object is to combinev such column selecting-mechanism with a denominational stop mechanism so as to arrestthe run of the a plurality of adjacent letter space positions contrivance with the carriag .To the above and other ends my invention consists in the features of construction.

Fig, '7 is a fragmentary plain view, partly in section, of a tabulator rac In various of the views parts are omitted and parts broken away.

I have shown my invent-ion as appliedto a Yost visible typewriting machine, but it will he understood that said invention may be adapted to various styles of writing machines.

Referring first to Figs. 1,v 2 and? of the drawings, the main frame of the machine is shown as comprising side plates 1, a slotted rear, and a two-part top plate 3. Type bars (not shown) are adapted to cotiperate with the fnont face of a platen 4 mounted in a frame or carrier 5 which is connected by links 6 with the side plates 7 of a carriage truck which with the carrier 5 composes the carriage or traveling element. Said truck further comprises a base portion connecting the plates 7 and composed of oppositely grooved guide rails 8 and 9 and connecting webs ,10. The guide rails cooperate with anti-friction balls 11, said ballslikewise co operating with fixed grooved track-ways 12 and 13 arranged atopposite sides of a transverse depression in the upper part of the machine frame. A crossbar or bracket 14, secured to lugs15 projecting inward from the side plates 1, has a depending lug 16 on which is pivoted at 17 a power device or spring drum 18, said drum being connected with the carriage truck by a. strap 19; The movements of the carriage in letter space direction are controlled by the carriage feed ing or escapement devices which comprise a swinging rack 20. Said rack is arranged shaped arms 21 pivoted at 22.0nlugs 23 'depending from the base of the truck, one at each end thereof. At its upper end each arm 21 is provided with a forward extension 2% whichis normally maintained in contact with a stop 25 by a horizontally disposed leafspring 26, said leaf spring being secured by screws 27 to the truck base and pressing down at its free end on a rearward plate 2.connecting said side plates at the beneath the carriage truck and extends longitudinally thereof, being supported on T-- 1 -.plates 1.

extension 28 integral with the arm 21. Normally the feed rack 20 meshes with a feed pinion 29 secured at the top of a vertically disposed shaft 30, said shaft being supported near its upper end by a plate 31 fixed to a cross arm 14 and bearing on its lower end on a pivot pin 32 secured to a lug 33 projecting rearwardly from the middle of a cross .bar 34, said bar being secured by screws 35 to lugs 36 integral with the side Operatively connected with the shaft near its lower end is a toothed escapement wheel 37, cooperating with which are escapement elements a or I dogs (not shown). The carriage feeding devices coact in a known manner to'cause letter space movements of the carriage and platen in printing direction when the printing keys are operated. Y

The manner above described of supporting the rack 20 is new but the other parts hereinbefore set forth are or may be old and preferably are likethe corresponding parts in the Yost visible machine.-

The tabulatingmechanism comprises a toot-hed'stop bar 38 of ordinary construction series or set ofdenominational 'ject upward above a slotted column stops,

supported on standards 30 rising from the rear of the carriage trucl Adjustably supported on the stopbar 38' are a plurality. of column stops. In the drawings four of such steps are shown and beginning at the lefthand. are numbered respectivelyv 40, 41, 42 and 43. As will be understood from Fig, 2 the column stops arestepped; that is, their operative faces project difierent extHtS' fIOIIl their support, the stop 40 pro jecting the shortest distance, the stop 41 projecting 'a somewhat greater distance, the stop 42 a corresponding distance beyond the stop 41 and the stop 43 an equal distance beyond the stop 42.--' In. other words, the steps or differences in length of the working faces of the stops are progressi e, each step being equal to the preceding step. Adapted to cooperate with the column stops are a stop levers are in the present levers 44 and proguide plate 46 which is secured to the rear portion of the top plate 3 and maintains the stops 45 a letter space distance apart. As appears from Fig. 2 the stops 45- normally are disposed in the rear of the series of stepped and are so arranged that when projected forward they will coiipcratc with one or another of the column stops, depending on.the extent of forward movement to 44. The steps proper-45. case the upper'ends of the .Which said stops 45 are subjected. The stop levers 44 are bell cranks eachhaving a vertically dlsposed rear portion which extends downward from the. stop end 45 and then curves forward, passing through a guiding slot or kerf 47 formed in a lug 47 integral with and extending downward from/the cross bar 34. From its guide slot each lever 44 extends horizontally forward with a slight upward inclination and near its forward end is curved slightly upward, terminating in a comparatively narrow end portion. There are ten stop levers 44 shown in the drawings, but of course a greater or less number may be employed. As will be 'undc1'stood from a consideration of Fig. 1, the levers 44 extend straight downward parallel with each other and a letter space dislance. apart for a short distance below the top plate and then are bent or offset laterally outward, the five right-hand lever arms inclining toward theright-hand side of the machine and the five lefthand lever arms inclining toward the left-hand side of the machine. Below the inclined portions the lever arms agaln extend straight downward and parallel, being a considerable distance 'apartso that .the horizontal portions which pass through the guide slots 47 are sep* arated enough to "provide a considerable amount of stock between each slot in the lug'47. Supported in said lug 47 is a rod 48 on which the levers'44 are pivotally supported. From Fig. 3 itwill be observed that some distance forward of their pivots the horizontal portions of the levers 44 fan outward so that their'forward end portions are quitewidely separated. These forward end portions are each confined in a vertical slotway 49 formed in a key stem 50. The key stem is vertically disposed and at its lower end terminates in a head 51 which supports a washer -52 of leather or the like. Fitting into the'slot 49 in the stem is a key plate 53, said key plate being secured to the stem by rivets 54 and terminating at its lower end just above the forward end portion of the associate lever 4-l-- as shown by dotted lines in Fig. 2. The key plates incline upward and forward from their stems, and the forward edge of each key to provide a set of stepped jcqually apart. Four of such stop faces are shownon each-key plate in the present instance, and beginning at the top and progressi n d ow n w a rd marked respectively 53, 53 and 53 (Figs; 2 and (3). The function'of the stop faces, is to assist in positively arresting the 'dentnninational stops in desired operating positions, as subsequently explained more at length The key plate terminates atits stop in a k or linger button There are ten of these keys arranged in a row as shown in Fig. 2% and ap n'opriately marked with punctuation marks and with numbers indicating denominations. The set of denominational keys forms a bank in rear of the regular l-ceyhoard and slightly elevated abovethe last bank of keys in said keyboard. Near their upper ends the key stems pass through and are guided by holes 56,formed at regu- I and 'rearward are lar intervals inthe horizontal portion of an angular plate '57, said plate terminating at itsrear in a vertical flange which at its ends receives screws 58, said screws securing the plate to lugs 59 projecting inward fromthe side plates 1. The plate 57 serves both as a guide for the key stems, a cover for certain of the partswhich are arranged below and'behind'said plate and also as a support for various devices presently to be described. The lower ends of the key stems 50 pass through'and are guided by holes formed in an angular guide plate 60, said plate extend- :ing from sideto. side of the machine and being secured at its endsto lugs 61 integral with and projecting inward from the side plates 1. The denomination level-s44 are maintained in normal position, as shown in Fig. 2, each by a coiled spring 62, one end .of which is secured, to the associate lever 44 and the other end to a bracket 63 fixed'by screws ti l to the frame plate 2. When in normal position the rear edge of the stop 4:5 on each lever or blade 4A isat the rear of its slot in the guide plate 46,".while the washer 52 onthe associate key stem is maintained in contact with the under face of the horizontal portion of the'guide plate 60.

It will be understood that each of the denominational keys when depressed will pro jectits associate;denominational stop forward into the path of the column stops; The carriage is automatically released by the operation of the denomination keys and means are provided for variably timing the carriage release so that it may take place after the actuated denominational stop has entered and isin the field or path of the selected column stop. Separate and independent/means are provided for Jsitively arresting the denominational stops after they .have been projected intothe path of the desired column stop. This is a highly important feature, as, hitherto, owing to the fineness of the adjustments required, it has frequently happened where stepped column stopsare employed and the denominational .stops are variably movable, that the actuated denominational stop has been pro. jected either a greater or less distance than the desired distance, causing a faulty operation of the mechanism.

Themeans set forth in the preceding par-' agraph include a U-shaped bail or member 65 which is shown detached in Fig. 5 and also appears in Figs. 1 to The member .65 comprises a-horizontal plate-like portion 66 having a forwardly projecting platformor lip 67 atits middle and a cut-ou't'or slot 68 in its rear face behind the platform 67..

Ears 69 upturned at the ends of the plate 66 are formed with hearing openings 70. A

horizontal extension 71 projo c ts rearward from, the righ t-hand car 69 and from the rear of said extension an arm 72 extends.

vertically upward and is bent atditlerent points'in its length so-that it is off-set outward ontoward the right. At the top of said arm 72 is formed an elongated slot 73 which coiiperates with carriage releasing" The" devices presently .to be described. bearing openings engage pivots 7d supported on cars 75, said ears being integral with the cross bar or bracket 34 and curving downward and forward therefrom. WVhen pivoted on the member 65 under ies the horizontal portions ivots 74L the base of the of the denominational levers 44 forward of the pivots 48 thereof. At each side of the slot 68 a bearing block 76 is mounted on the base bar 66 and is secured theretoby screws 77. The blocks are formed with holes 78 which receive a rod 79 Whereon aplurality 'of column selecting. levers are pivoted.

Three of such levers are shown in the drawings and numbered-respectively from left to right 80, 81 and 82. The column selecting levers while generally resembling each other, differ in certain respects. Each of said levers is formed at its rear end with a hole 83 .through which the pivot rod 797 passes. Below the hole 83 the lever is rounded, the rounded portion being received in the slot68. For'ward of the rounded.

As appears clearly from Fig. 2, the

of inclination, and the edge 86 of the lever 82 a still greaterdegree. The actuating edges normally lie above the top face of the platform or lip 67 and .the degree of inclination of the three actuating edges upward from this face isprogressive. Forward of the actuating edges the levers are cut-away so as to provide body portions of normal width, the body portions extending horizontally. forward and also inclining laterally to different extents. Near the front, the body portions turn vertically upward and then again project horizontally forward, terminating in a narrow finger which, as clearly shown in Fig. 4, engages in a slot 87 formed in a key stem 88. The lower end portion of each key stem. passes through a guide opening in the plate 60 and l is provided-with a head similar to the heads of the denominational key stems. Each key stem 88 is maintained in normal position by acoiled spring 89 which presses at its lower end against the top of the plate 60 and is secured at its upper end in a hole in the key stem... The upper end portion of each keystem passes througha guide opening inthe plate 57 and'is bifurcated to provide a slotway 90 which receives akey plate, the lower end portion of saidkey plate being fixed to key stem 88.

column selecting keys e numberedrespectively 92, 93 and 94.

In addition there .is or may be provided a fourth key plate corresponding to afourth column, said key plate being secured like the other key plates to a spring-pressed The key stem 88 of the fourth column key, however, isnot connected with a column selecting lever, there being only three such levers. As shown in F 3 the three column selecting levers are arranged alternately with denominational levers so that the key stems 88 and key plates secured thereto project upward between the front end portions of these denominational levers which are near the middle of the machine. The key plate 95 and its key stem are similarly arranged in the space between the two denominational levers next to that occupied by the key plate 94: and its key stem. At the front, the column selecting levers are maintained properly spaced apart by their key stems which in turn are controlled by the guide plates 60 and 57. At the rear, the column selcctingleversare spaced apart by spacing sleeves 96 surrounding the pivot rods 79 (Fig. 1). I

Each key plate is provided with a finger button or key 97. From an inspection of Figs. 2 and 3 it will be seen that the set of column keys 97 are in a row behind and slightly above the set of denominational keys 55. The tops of the column keys 7'? may be and preferably are marked with indices to show the column to which they appertain. Such marking appears on the key 07 shown in Fig. 4; but in Fig. .3 the markings are omitted from the tops of the keys for the sake of clea-rncss.

Each of the key plates of the column selecting mechanism formed at its rear with a curved edge or cam 98'. Each cam 98 terminates substan tiallyvertically for greatestextent. from the vertical.

stop face 09 adjacent to the key stem 88. From the stop face 99 the cam face curves upward .and rearward and a short distance, terminating at its upper end in a horizontal locking face oredge 100. At its front side all the column key plates except the fourth are formed with cam faces or curved edges which are inclined oppositely from the rear cam faces. The rear cam faces-are all alike but the front cam faces incline at different angles from the vertical, the difference bemg a progressive one as will be best understood froma consideration of F igs. 2.

The cam face 101 at the front'of plate 92 'is curved forward to the The cam face 102 atthefront' of the key plate 93 has a less degree 'of forward inclination than thecam plate 101 while theeam face 103 and 6'. the key on the key plate 94 in turn is nearer .the

4 plate 57 behind at the bottom in a horizontal then extends releasing devices in order to The front edge. of the fourth plate is vertical and does not cam face. column key act as a cam. The rear cam faces 98 are adapted to cooperate with a locking plate 105 which extends lengthwise above the the column selecting keyplates and is provided at its ends with lateral studs 106 which are pivotally supported in bearing openings in angular plates 107 secured by screws 108 to the top plate 57' igs. 2, 3 and 4). The lockingt plate 10 is vertically disposed and .atis top is curved or bent over forwardand downward, thus providing an engaging lip which terminates in a locking face 109. Forward of the key stems 50 and extending above the plate 57 lengthwise thereof f and beyond the end denominational keys,is a stop plate 110 which is provided atits ends with lateral studs 111 seated in bearing openings in angular bracket-s 112 secured by screws 113 to the plate '57 (Figs. 2, 3 and 6). The plate 110 'is movable b the cams '101, 102 and 103 todifi'erent positions to co-act with the stepped stop faces atthe front of the denominational. key plates. The pivoted plates and are connected by a coiled spring. 114, said spring being horizontally disposed andaznt its rear hooking into an eye 115 pro ecting forward from the'front face ofth plafia 105, the front end of the spring 1H hotiking into a similar eye 116 projecting, rearward from the locking plate 110. The spring 11 1 tends constantly to draw-the plates 105 and 110 together or swing them toward each other on their pivots. The result is that as shown in Fig. 2 the plate is normally maintained in contact with the cam edges 98 on the column selecting key plates, while the plate 110 is normally maintained in contact with the front of the key stems 50 and 88 and justbelow the cam edges at the front sides of the column selecting key plates.

The member 65 and the column levers are adapted to set variably selecting the carregulate the timing of the carriage release to correspond with the variable operation of the denominational stop devices. Thecarrlage releasing devices comprise a universal'bar 117 which underlies the front end portions of the denominational stop levers and is adapted to be actuated by each of said le vers. The universal bar 117 is, as \Vlll be understood from Figs. 1, 2 andf3. a part of a pivotally supported universal bar frame which further comprises angular side arms 118 connected at their rear. ends by a cross plate 119. The universal hanframe is piv- Oted on th epins 74, the outer end-portlons of said pins being reduced to provide supports for Said frame. The cross plate 119 overlies the two sets of tabulator levers and is bent downward at its ends to connect with the side arms 118. The pivot pins 74 are retained in place on the ears 75 by set screws 120. By loosening the set' screws the pivot pins 74 may be removed, enabling both the member 65 and also the universal 'pins 128 supported on lugs 129 which curve downward and forward from the under side of the bracket 14. The pivot pins 128 are adjustably secured in place by set screws 130. The cross bar 126 of the releasing frame is provided with transverse fingers 131 and 131. The finger 131 extends upward slightly above the feed rack 20, normally vlying somewhat forward of saidrack as shown inFig. 2; while the finger131 extends downward from the cross bar in line with the finger 131. The depression of any denominational key 55 and the actuation of the connected denominational lever 44; rocks the universal bar frame, raises the link 122 and swings the releasing frame upvard on its pivots 128,

thus bringing the finger 131 against the feed rack 20 and swinging the latter rear ward on its pivots 22, overcoming the springs 26 and causing the teeth of the feed rack to disengage fronrthe feed pinion 2%), thereby permitting the carriage and platen to be drawn freely leftward by the spring drum. After the arrest ofthe carriage gull vthe release of the actuated denominag'ional key,-the denominational devices will be re stored'to normal position by the sprin'g 62 whilethe universal bar frame, releasing frame and the link connecting them will be restored to normal position by springs 132 secured to the rear vertical face ofthe plate (it). The feed rack 20 will concurrentl y be restored into mesh with the feed pinion 2!) by the springs 26.

By variably setting the actuating stud 1'23 carried by the link 122 at different points along. the slot 124 the timing of the carriage release may be varied, This variable settionless during is retained at the rear end of the slot 124 by reason of the fact that the arm 72 is constantly impelled rearward byacoiled spring 134, the front end of which is secured to the arm '72, the rear end being secured to a in 135 depending from the bracket 14. he spring 134 acts on the stud 123 through the link 122, pin 133, slot 73 and arm 72. It will further be apparent that said spring acts through the arm 72 on the entire member (55 with which said arm 72 is integral and normally maintains said member in the position' shown in Fig. 2.

Referring to the action of the column keys 97 in positioning the stud 123 at different points along the slot 124, it will be.

apparent that when any one of the column keys, except the fourth, is depressed it will first operate on its associate lever 82 to swing said lever downward on the pivot rod 79. During the first part of this downward movement of the lever 82, the frame 65 on which it is supported will remain motionless. When, however, the-lever has' been swung far enough to bring its inclined actuating edge into contact with the platform (37, the supporting frame 65' will be taken up and thereafter will participate in the motion of the lever 82, said frame rockin on its pivots 74 and causing a forwar swing of the arm 72. Said arm 72 through the pin and slot connection 133, 73 will operate to swing the link 122 forward about its point of (:OllntCtlOIl with the extension 121 as a center, thereby moving the stud 123. forward along the slot-way 124 in the; releasing frame, said frame remaining mothe setting operation of the link 122. It will be apparent that the extent of forward movement of the stud 123 will depend on the extent of forward swing of the arm 72 and that this in turn will vary according as the first, second orthird column key is actuated. .lVhen the Illlllle her one column key is actuated it will move comparatively a short distance only before the actuating edge 84 contacts with the platform 67 and picks up the "member 65. When the number two colu inn 1 eyis actu ated the lost motion-before thenctuating edge 85 picks up the member (55 will be. twice as great; while when the numberthree column key is actuatedthe lost motion between the actuating edge 86 and the plat-- 'f()ll1'l (i5 will be three times as great asin the first instance. From what has been said, then it will be clear that when the number one column key is actuated, the stud "123 will be moved forward in the slot-way key is actuated. It will furthermore be unof the releasing frame, which center passes through the pivot pins 128; and that consequently a greater motion will be communicated to the releasing frame carrying the finger 121 when the .stud 123 is moved up- .ward by the rocking of the universal bar frame than will be communicated to the said frame by an equal extent of upward move ment of said stud when said stud is set farther from the center of motion passing through the pivots' 128. For example, if the stud 123 is set at the rear of the slot and one of the denominational keys is actuated, the releasing finger 131 will move quickly into contact with the rack 20 and will swing said rack out of mesh with the pivot 129 soon after the actuated denominational stop 45 has begun to move forward from normal position and while said stop 45 is in the path of the fourth column stop 43 and prior to said stop 45 entering the path of the third column stop 42. Supposing on the other hand that the stud 122 has been set at the front end of the slot 124 by the actuation of the number one coluniri key 97, then the releasing of the carriage, brought about through upward movement communicated to the stud 123' from an actuated denominational key 55, will take place much more slowly and not until the actuated denominational stop has moved forward across the path or field of the fourth, third and second column stops and into the field of the first column stop 40. Following the same principle, if the link 122 and stud 123 be set intermediate theirrearmost and foremost positions lengthwise ofthe slot-way 124, then a subsequent actuation of a denominational key will effect the release of the carriage after the actuated denominati'onal stop has entered the field of the corresponding column stop (whether that stop be the second or third column stop) and while said denominational stop is still in said field. It will be understood that during the carriage releasing operation .the stud 133 on the link 122 will move upward in and be guided by the slot 73, while on the return of the parts to normal position the stud 133 will move downward in the slot 73 to its normal position near the lower end of said slot. During releasing operations the arm 72 is motionless so that the slot 73 serves as a relatively fixed guideway for the stud 133 and the link 122 and thereby maintains the stud 123 set in its:

predetermined relationship with the slot 121.

The movement of the link 122 and stud 123 to different points along the slotwvay 124 and the consequent timing of the release having been explained, the manner of res taining or setting said link and said stud in the positions to whiclithey have been moved" may be referred to. The setting means comprise the spring-controlled locking plate 105 and the co-acting cams 98 and stop fa'ces 100 on the column key plates. When one of the column keys 97 is depressed to swing the stud 123 lengthwise of the slot 124 in the. manner already described, thevassociate cam 98 acting against the forwardly extending lip on the plate 105, will swing said plate rearward on its pivot againstthepull of the spring 114. The rearward swing of the plate will continue until the upper end of the cam 98 passes below the stop face 109 on said plate, whereupon said plate will snap forward under the pull of its spring 114 over the stop face 100 on the actuated key plate. At substantially the same time the stop face 99 will contact with the top of the plate 57, thereby arresting downward movement of said key plate. Since the key plate cannot at this time move upward, owing to the co-action between the stop faces 109 and 100, it will be clear that it will be locked or retained in depressed or abnormal position, and that the parts controlled thereby, including the link 122 and stud 123 will be set or locked in abnormal position also. As long as the depressed column key 97 and associate parts are retained locked in abnorma. position it will be understood that actuation of any of the denominational keys will operate to release the carriage and arrest the same in the corresponding denominational position in the particular column with which the depressed and locked column key 97 is associated; that is to say, if the third column key has been depressed and locked and thereaftci. a denon'iinational key is operated,

the carriage will be released and arrested in the appropriate denominational position in the third column. After the numbers or other characters have been printed in the third column, if the carriage be retracted toward the right and subsequently one of the denominational keys be operated, the carriage will be released and arrested at the corresponding demmiiuational position in the third column. This construction. it will be apparent. is a convenient one where as frequently occurs. a successive series of numbore of the same or difiercnt denominations is to be printed in the same column. for it enables this sort'of work to be done by manipulating the denomimitional kcysaud the printing keys after only a single preliminary UPOI'EIflOIl of the appropriate column key. The actuated column key will be retained lockcd in depressed position until another of the column keys is actuated. \Vhen suchactuation takes place the associate (am 98' will swing the locking plate 105 rearward on its pivots. carrying the locking face 109 out of the path of the co-acting locking face 100, whereupon the depressed c lumn key and positions whereby the denominational stops 45 are positively arrested independently of the carriage releasing or other devices in position to cooperate with selected column stops, will now be explained Said separate and independent means includes the arrest ing device or stop plate 110 the series of stepped stop faces on the denominational key plates (which stop faces co-actwith said stop plate 110) and the cam edges on the front of the column key plates (which cam edges variably, position thestop plate 110). As has been described, the front edge of the fourth 'colum-n key plate 95 isvertical. (.onsequently when the fourth column key is depressed the locking plate 110 will not be affected, the result being that a subsequent actuatlon of one of the denominational I keys 5:) will cause the associate stop face 53 to contact with the top of the plate 110 and a rrest positively the denominational key and connected parts. The parts are so constructed and related that when this posi tive arrest takes place the actuated denominational stop 45 will be in the field of the fourth column stop and will be positively arrested in said field in position to co-act with the fourth column stop 43' and with no other column stop. On the other hand, if the first column key be actuated the cam 101 at't'he front oii the corresponding key plate will act against the upper part of the locking plate 110 and will cam or swing said locking plate forward on its pivots. The swinging movement willcontinue until the .upper end of the cam 101 is reached. at

which time thetop of the plate 1 It) will be in its final arresting position directly beneath the stop face-5E5 on the denominational key plates. At the same tinie that this forward swinging of the stop plate 110 is taking'place .the lockimg plate .105 is being swung rearward and the result will be that the stop plate 110 will reach the limit of its forward movement at the same time that thclocking or detaining device or plate 105 snaps forward to lock the number one column key plate in depressed position. it will be. seen that this locking of the key plate. will operate to set the stop plate 110 in the desired abnormal position so that when sub-' sequently a denominational key is actuated it will be arrested by the co-action of the associate stop face 53* with said stop plate 110. When this arrest of the parts takes place the actuated denominational stop 45 denominational key will end with the positive arrest of said key and actuated parts up to and including the associate de-.

nominational stop 45, said stop bein arrested in the field of the approprihte co umn stop. It will further be apparentthat the positive arrest of the denominational stops in the fields or paths of one'or another of the column stops is effected entirely independently of the releasing devices, notwithstanding the fact that therelea'sing of the carriageis brought about automatically by the operation of the denominational keys and after the releasing devices may have been previously set to time the release by the operation of one or another of the first three column keys. The actuation of the fourth column key does not operate directlyeithcr to set the releasing devices, including the stud 123. or to set the stop plate 110. But indirectly, the fourth column key does operate on these parts for the reason that the actuation of the fourth column key Will serve to release both the stud 123 and the stop plate 110 from positions in which these parts may be setas a result of the prior actuation and locking down of one of the first threecolumn stops.

ivssociated with my improved tabulating mechanism 1 have shown novel carriage retarding devices which may be employed with various styles of tabulating mechanism other than that shown, or in other connections where they may be of service. The novel retarding devices have to do more especially with the connections between the retarderproper and the carriage. Said conncctions con'iprise a toothed retarding bar or rack 136 which preferably is entirely separate and distinct from the carriage feed rack or other carriage feeding devices. l\s will be understood from Figs. 1, 2 and 7 the bar 136 is arranged lengthwise of the carriage truck and beneath the same, being slidably connected with lugs .137 depending from the carriage truck near the ends thereof. The bar 136' is provided near its ends with transverse slots 138 which receive headed screws said screws passing upward freely through said slots and entering tapped holes in the bottom faces of the lugjflf. By this construction the rack bar. is confined between the heads of the screws 139 and the bottoms of'the lugs 137 and'is capable of a limited sliding movement on said screws transverse of the. direction of the carriage travel.

,Coiled springs 140 supportedon screws 141 screws 139.- The contact of the last two,

parts determines the normal position of the rack bar 136, said normal position being illustrated in Fig. 2. From this figure it will be seen that the tabulator rack bar 186 is arranged in rear of and slightly below the feed rack 20 and that the teeth of the bar 136 are at its rear side and oppositely disposed from the teeth on the feed rack 20. The bar 136 is adapted to be actuated by a spring finger 143 which is secured by a. screw 144 to the rear face of the finger 131 at the lower end thereof. Said spring finger extends upward behind the fingers 131 and 131 and near its top is bent rearwardly under the feed rack 20, ter ininating in a short vertical engaging portion 145 which normally lies a short distance in front of the forward edge of the rack bar 136. When the carriage releasing devices are operated by any of the denominational keys 55. the upper end portion of the spring finger 143 moves rearward, bringing the engaging end 145 against the bar 136, and as'the motion continues forces said .bar to slide rearward against the pressure of its springs 140. The construction and mounting of the spring finger is such as to permit of some extent of lost motion after the end 145 has contacted with the rack bar 136 before rearward movement of said rack bar begins. By this lost motion construction the necessity of a finely adjusted relationship between the carriage releasing devices and the connections to the rctarder is avoided. The teeth of the rack bar 136 are normally disconnected from, but are adapted to mesh with, the teeth of a pinion 146, said pinion being connected in any desired way with the retardcr devices proper. In the present case the retarding devices proper are arranged in a cylindrical box or casing 147 having an elongated vertical hub 148. Said hub, as clearly appears in Fig. 1, is provided at its top with a lateral off-set 149 which receives headed screws 150, said screws entering the rear ofthe cross bar or bracket 14, and thereby rigidly securing the casing 147 tosaid cross bar and thus to the machine frame. The pinion 146 is or i may be secured at'the top of a shaft which bears in the hub 148, whence it appears that the pinion has .a rigid bearing and a fixed axis of rotation. It is not deemed necessary shown in my pending application Serial No.

303,654 filed March 1, 1906 may be employed,- but any other desired style of retarder may be made use of and arranged to be connected with the carriage in the manner illustrated and above described. From what has been said it will be apparent that when the rack bar 136 is slid rearward during the carriage releasing operation the teeth of said rack bar will be brought into mesh with the rigidly supported pinion 146 and a connection between the carriage and the retarding devices proper thereby effected, so that when the release occurs and the carriage starts to run leftward it will do so under the control of the retarding mechanism. After the carriage has been arrested and the actuated denominational key released, the spring finger 143 will swing back -to normal position along with the releasing frame on which it is supported, thereby; ermitting the rack bar 136 tobe restore, to normal position by its spring 140.

My improved carriage retarding devices possess several advantages over retarding.

devices hitherto employed. The provision of a retarding rack separate from the carriage feed rack avoids Wear and liability of breakage of the teeth of the-feed rack from being connected and disconnected to the carriage retarding devices. Furthermore, by employing a movable retarding rack of the character shown and adapted to be connccted with apinion or other device corresponding with the pinion 146, I am enabled to avoid the necessity of moving the comparatively heavy retarding devices proper and thus reduce the energy necessary to be expended in bringing the retarding mechanism into operation.

It will be seen that by my present invention I combine. with the carriage releasing means, means independent of said releasing means for variably arresting certain of the tabulator stops when they are actuated and at the end, of their movement; that said arresting means comprises an arresting device:

that means are provided for moving said' arresting device to any one of a plurality of operative positions; that means are provided for locking said arresting device in its operative positions; that the arresting means including said arresting device remains qui- .escent during the actuation of the tabulator stops; that the arresting means is contactive with different portions of the stop actuating mechanisi'n to arrest variably the actuated tabulator stops; that the arresting device itself is in the forln f a bar or plate pivotally mounted on the frame'of the machine; that it. controlled by means for turning it variable extents on its pivot; that the controlling means is actuated by keys; thatsaid controlling means include a cam mechanism;

that said cam mechanism includes a series of progressive cams; that the arresting de- .vice and controll ng mechanism including said cams are: adapted to belocked or detained in abnormal positions; that the locking or detaining means includes a locking bar or plate, said locking ba'r being pivotally supported on the frame of the machine; that said' cams are on key plates; that said key plates are controlled in the present instance by column keys; that said key plates are purpose to predetermine further provided with devices orcams for actuating said locking bar; that said locking bar and said arresting bar are constantly urged toward each other by a connecting spring; that the arresting bar operates with predetermined stepped stop faces -on keyplates controlled by denominational keys, sa d-arresting plate; being moved for this (1 arresting positions; that said arresting bar is set, locked or detained in predetermined positions by said locking bar or plate; that both sets of cams are controlled by the column keys, one of the set's being progressively arranged ,while the cams ot the other set are all alike;

that the carriage feeding devices comprise a spring-pressed'feed rack and an intern'ieshmg horizontally disposed feed pinion; that the releasing means comprise a pivotedfinger ,movable to swing said rack rearward out of tabulator stops; that means are provided for variablytiming the operation of the releasing means, which variable timing means are separate from the tabulator stop actuating means; that means including a key are pro vidcd for variably actuating certain of the tabulator stops; that there are mechanical connections between said key and .thecarriage'releasing deviceor' finger; that there are means for varying saidconne'ctions so that substantially the same extent of movement is imparted to'said releasing devices for varying extents of movement of said key; that in the present instance-said key may be any one of a set of denominational keys; that the varying means include de-v vices -for variably setting said link at ditfferent predetermined points lengthwise of a slot formed in an arm integral with the releasing frame which carries the releasing finger; that-the column keys control levers, provided with progressively arranged in- 'clined actuatingfaces or actuators; that a inovable frame is' provided :wkich'is variably tion of a carriage,

- and their arrest taking placewhile-said demovable by said actuating faces or actuators;

that said movable frame is pivotally mounted; that said column key levers are pivoted on said pivoted movable frame; that said frame is operative on said link with which it is connected by a pin and slot connection; that a carriage retarding mechanism is provided comprising a retarder which is fixed to the frame of the machine below the top plate thereof; that a retardcr rack coiiperates with said retarder, said rack being independent of the-carriage" feeding devices; that said'rack ,is spring-pressedand is slidably supported on said carriage underneath the same by screws which pass through the slots in, said rack; and that the teeth of said retarder rack are oppositely directed from the teeth of the carriage feed rack.

It will be apparent that various parts of my invention may be used without"other parts. mechanism may be employed with a single coiiperating stop instead of a set of denominational stops.

Various changes in construction and arrangement may be made without departing i from the scope of my invention.
